Science-backed health benefits of Mulberry Seeds

Mulberry seeds are the tiny, oil-rich reproductive components found within the fruits of the Morus species, known for their high concentrations of antioxidants, polyphenols, and essential fatty acids. In recent years, mulberry seeds have gained recognition as a potent superfood, with scientific studies highlighting their wide-ranging health benefits. Rich in bioactive compounds such as flavonoids, anthocyanins, and resveratrol, these seeds contribute significantly to human wellness. Research has shown their antioxidant and anti-inflammatory properties to be effective in reducing oxidative stress and combating chronic diseases like cardiovascular conditions and certain cancers. Furthermore, the presence of resveratrol—a powerful polyphenol also found in grapes—amplifies their potential in supporting immune function, slowing aging processes, and improving metabolic health. As scientific attention grows, mulberry seeds are being explored not only as a traditional remedy but also as a functional ingredient in modern health supplements.

Nutritional and Phytochemical Composition of Mulberry Seeds

Mulberry seeds are packed with essential nutrients and bioactive compounds. Rich in protein, fiber, healthy fats, and antioxidants, they offer a unique phytochemical profile that supports various health functions.
